Hi, Been long time fan of KIS, IMO very strong AV, I trusted it to keep me safe. Recently KIS conflicted with too many apps: tried exclusion, tried apps KIS 'on & off' worked with KIS off, not work KIS on! New to AV world is MBAM 4.0! I feel MBAM (resident) + KIS would add little protection. Currently MBAM/KIS conflict I feel WD & MBAM (resident), probably would not match the protection, from just KIS I have a 'lifetime license' MBAM. Uninstalled KIS! Installed MBAM 4.x & MBAM browser extensions. CURRENT The community here seems divided, MBAM stand alone, or MBAM with other protection. Pretty much started here at Wilders & never been infected! So MBAM alone, sans traditional AV's FW's, anti this or that? or Uninstall MBAM allow another AV (to register with Windows Security Center) then install MBAM? I also believe if MBAM is going to satisfy Windows Security Center, then it's an AV, & should be tested, along with others at: Av Comp, VB etc.
